Plant Classification

9

Plant Classification • Although all plants share common characteristics, they can be classified into groups: Non‐Vascular and Vascular plants.

• Vascular plants can be classified into three subgroups:

Seedless plants

Seed plants ‐ Non‐flowering seed plants, ‐ Flowering seed plants

10

11

Non‐Vascular Plants • A non‐vascular plant doesn’t have specialized tissues to move water and nutrients through the plant.

• So these plants depend on diffusion to move materials from one part of the plant to another (cell to cell).

• Diffusion is possible because non‐vascular plants are small.

• Mosses, liverworts and hornworts are examples of non‐ vascular plants.

12

13

Vascular Plants • These plants have specialized tissues to move materials through the plant.

• These tissues are called vascular tissues, and can move water and nutrients to any part of the plant, which allows it to be of any size.

• Vascular plants are divided into: Seedless plants and two types of plants with seeds.

• Gymnosperms are non‐flowering seed plants.

• Angiosperms are flowering seed plants.

14

Animal Classification

15

Animal Classification • The animal kingdom is divided in two major groups: Invertebrates and Vertebrates.

• Invertebrates, are those animals that do not have a backbone.

• Invertebrates live in water and on land.

• There is a great variety of invertebrates, more than one million different kinds.

16

17

Invertebrates • These millions of invertebrates can be divided into 12 phyla.

• Here are 8 of the most important ones: Cnidaria: Hydras, jellyfish.

Platyhelminthes: Flatworms.

Porifera: Sea sponges.

Arthropoda: Insects.

Mollusca: Clams, snails, squid.

Nematoda: Roundworms.

Echinodermata: Starfish.

Annelida: Leeches

18

Simplest Invertebrates • The simplest invertebrates live in water, the place where animals first appeared.

• At first sight, these invertebrates may look as plants. Example: Some cnidarians (anemones and corals).

19

Sponges and Cnidarians • They are brightly colored and sessile like plants (they don´t move from place to place).

• One characteristic of animals is the ability to move around.

• However, sponges, anemones and corals do move when they’re young and they don’t move when they’re adults.

• Sponges feed by the passing of water and trapping of food particles through pores in its body.

• Most cnidarians have armlike structures called tentacles with stinging cells around the mouth that help them capture the prey. Although they don’t have a brain they have nerves and muscles.

20

Flatworms and Roundworms • Flatworms are the simplest worms. If you cut a flatwom by the middle, one half looks like the other.

• They have a head, a tail, and only one opening, the mouth.

• Planarians are flatworms that live in fresh water.

One feature you can see is the “eyespots”, as part of the nervous system, that includes a simple brain.

• Some flatworms (plateworms) live inside the body of another organism. They feed off digested food from that organism.

• Roundworms have a tubelike body, that comes to a point at each end.

• They have a digestive system with two openings (mouth and anus).

• Roundworms may live in soil, fresh water, or salt water, and also inside other animals.

Complex Invertebrates

MOLLUSKS • They are found on land, fresh or salt water.

• They have soft bodies covered with a mantle. In many mollusks, the mantle forms a hard shell.

• The organ systems are underneath the mantle.

• They feed by moving around through a “foot”.

• You can tell different classes of mollusks depending on the food and the shell.

• Examples: Snails, clams, oysters.

• Octopuses and squids are the most complex class of mollusks. They have tentacles to move and to capture prey.

• Octopuses have no shell. Squids have a shell on the inside.

25

26

Complex Invertebrates

Segmented Worms • Earthworms and leeches are segmented worms.

• Their bodies are made up of segments, or rings.

• They have a tube‐shaped digestive system with two openings.

• The worm has a circulatory system with hearts and blood vessels. They also have nerves.

• These structures enable the animal to respond to light, temperature, and moisture.

Earthworm

27

Complex Invertebrates

Equinodermata • They are very different from any other invertebrate.

• One main difference is a kind of water‐pumping system.

• Water‐filled vessels extend from the mouth into the arms of the animal.

• The water is pumped to the tube feet, structures that help the animal grasp and move.

28

Complex Invertebrates

Arthropods • Two‐thirds of the species on Earth are arthropods (around 1,000,000,000).

• Members of this phylum live in almost every part of Earth.

• One group of arthropods, the insects, holds more different species than all the other species of living things combined.

What do Arthropods have in common?

• They have jointed limbs, including legs for walking and jumping.

Some have jointed wings, flippers or claws. Their bodies are in sections.

• They have an outer skeleton, or exoskeleton.

• The major classes of the arthropods are: • arachnids, insects, and crustaceans.

ASSIGNMENT

Invertebrates • Investigate the uses of invertebrates in society, the good and bad effects humans get from invertebrates.

• Publish it in your wiki.

• Deadline: Monday, August 31st.
